DISMOUNTABLE RIM.

Specification of Letters Patent.

' Patented July 18,1916.;

applieaiion mea June v'1, 1915. serial No; 32,783.

To all'llhom itmag fBe'git known `that I, ALERT 'J. GLAU,a

c1tize`n' of the-' UnitedStates, residing at San Arde, ,in thecounty, of Monterey and Stateof California, have invented a new and useful Bismountable Rim, of which the l following is a'speciication. My l` rim for automobilesv and motorcycles, vthe ob- -nvention relates' to a" dismountable ject of my ,inventionibcingto provide arim of this character vhavingnovelv fastening and releasing-,means and whichmay be more readily. and quickly-'detached to permitof repairs to the tire than is possible with rims 1n use at the present time. l v

1 attain the objects of my invention byv 'the mechanisml illustrated in the accompany- Figure l. is` a section illustrating my in-A- vention; Fig. 2 is anelevational view with a portionof the rim' shown' in section; Fig.

3 is a cross section Online 3--3of Fig.'2; Fig. 4 is a detail otcap member 10; Fig. 5 is an elevational view of a modied form of the invention, partly in section, Fig. 6 isa cross section online 6-,6 of Fig. 5, the latter two views illustratinv .the vmodiied form ofthe invention applic to lighter tires:

' Similar characters of reference indicate4 similar parts throughout the several views. Referring to the accompanying drawings, I provide a wooden felly l, over which is mounted a metal band 2,- while over band 2 l is mounted the tire engaging rim 3. I provide a boss or enlargement@ at suitable intervals in rim 3; the metal band 2 being provided with a corresponding depressed -portion 5 into which boss 6 extends; and wooden telly 1 being provided with a corresponding recessed portion 4 for portion 5 of the b and 2. A tapered recessed portion 7 is provided in -boss'6,into which projects the "tapered end of plunger 8, as illustrated in Fig, 1 The plunger 8 is-mounted inicasing 9. Casing 9 is covered by cap 10,v which is pro-` vided with a projection 14, adapted toengagevv in a grooved portion 15'- extending lengthwise lof plunger *8, and openingv into a grooved portion 16, at'right' angles thereto,4

as shown in Fig. 1. Plunger 811s normally and resiliently held in engagement in recessed portion 7 of boss 6 by a spring 11 opposite ends of which press'against shouldered portionw12 ofthe plunger and the 1nner portion of capr 10. Plnnger 8 isrprovided with a suitable handle 13. A subitable reinforcingband 17 may be yprovided for strengthening thev wooden felly 1 at its recessed portion and to support the'plunger 'casing'. Mountedi'n grooved portion'19 of 6 0` rim 3 is a detachable rin'memberlS, having a depressed portion '2O engaging in rim 3,

.as illustrated in Fig. 3.

In the modied form -of my lnvention lllustrated in Figs. 5 and 6, which is used 65 l on lighter tires, such -as might be used for motorcycles,l the wooden felly v1 and metal band 2' arereplaced'by a fixed rim or felly-.\ bandl 1-a, as shown in the drawings. `A. suitable number of plungers are provided for each tire, accordingto its charj acter. On a 4x34 and smaller tires, six plungers are sufficient. Onlarger tires as many aseight or ten plungers would be required. l l 75 The operation-,of the invention will vbe understood from an examination of the ac coxrlpanying drawings.I

-o remove the tires the/ plungers are turnedsuiciently to Ycause projection 14 of cap 10 to engage in the transverse grooved portion 16 of the -plungerand retain it in ltsinward position, out of engagement with member 3, when the rim may bestarted by a good jerk withboth hands, without 'the use of a hammer or similar tools. With' all the-plungers drawnto their outward position, the rim is'released so that it may be quickly taken olf or put ron the wheel. The @o valve stem extends through an elliptical slot extending' through the rims (not illustrated) to allow the valve stem to be readily moved." inward orA outward enough toloosen rim, so that it can be pulled off from the wheel on the opposite side from the valvestem, and then theY valve stem can be slipped out of its slot.v v

What I claim is:

1. In a dismountable rim having an annular rooved tire-engaging member, a detachab e ooved rim member, a metal band disposed etween the tire-engaging member and the telly, anda felly, a plurality of radially disposed plunger casmgs, caps for the casings, said caps having a proj ect1on, 'a plunger mounted in each of the casin'gs, said plunger .having La substantially L-shaped .I groove adapted lto receive the proJectlon orA l the cap, a. spring normally pressing 4the 111-0 plunger into engagement with the tlre-engaging member, and oriced portions for the -puued toward the heb of the Wheel and sulA plunger, whereby the plungers may `be quickly secured either in engaged or nonengaged positions relative to the rim.

2. In a dismountable rim an inner tire-engaging member having a series of relatively large bosses spaced at a substantial distance apart, each having a tapered opening, a felly, la metal band disposed between the inner member and the felly and having substantially depressed portions over the bosses,A tapered plungers engaging 1n the b0sses,

springs bearing on the plunger members, grooved means in the plungers for locking same out of engagement With the bsses to permit of quick dismounting of the rim, and a handle Secured to the plunger for Withdrawing same from engagement with its boss.
